Odor Neutralization at Methanization plant in the Vendée

Year: 2021

Methanization plant in the Vendée

Technical data:

  • Incoming waste: 37 000 tons/ year
  • 23 000 tons of cattle manure
  • 1 400 tons of poultry manure
  • 2 800 tons of grain sorting difference coming from agricultural cooperative Cavac
  • 6 500 tons of white water and flotation grease coming from the water treatment plant shared by Agrial and Bonilait
  • Some occasional products

Implemented Odor Treatment:

  • Odor neutralization of a process building using industrial spraying of an odor neutralizing reagent. This building contains a grinder and two conveyors of organic material that feed a mixing tank. 6 misting heads are installed above these odor sources.
  • Spraying odor neutralizer at a low concentration reduces odors at their source (inside the building) before any phase of dispersion (residents) during the stage of organic waste grinding (manure, vegetable residues, corn shreds, etc.)
  • The formulation of the applied neutralizing reagent was specifically adapted to the encountered odor issue.
  • The engineering solutions only function during two daily stages of organic material grinding.
  • This control provides the customer with an optimization of reagent and water consumption. The installation can also be operated with predefined time slots.
